Royal Decree 679/2006, on used industrial oils, established the extended producer responsibility (EPR) in the management of used oils. In 2015, the organization of the EPR is modified with the entry into force of Royal Decree 110/2015, on waste electrical and electronic equipment (WEEE). In this context, the results of the evaluation of the efficiency of EPR differ from those previously obtained, by which the EPR in the management of used oil constitutes a standard of recycled material (SRM) applied for the whole sector of lubricants. From the perspective of waste oil management, the competition between different integrated management systems for waste oil justifies that the result of the evaluation of the efficiency is indeterminate. If the lubricants market is considered it is shown that a demand for more differentiated lubricants, is incompatible with the SRM.
